See Something ?

The FBI is advising law enforcement to remain on the lookout for homegrown attackers and so-called "lone wolfs" inspired by terrorist organization.  The U.S. State Department has issued a world-wide travel alert and the FBI is warning of potential copy-cat attacks as fears over terrorist strikes during the busy travel season continue to mount.

A lone wolf is a wolf that lives independently rather than with others as a member of a pack.
Typically older wolves driven from the pack, perhaps by the breeding male, and young adults in search of new territory. 

In the case of San Bernardino, Marquez, 24, a neighbor of killer Syed Farook, is accused of illegally purchasing a pair of rifles that were used in the attack. He also is accused of the more serious offense of conspiring to provide material support to terrorism.

Rafia Farook, the killer's mother, lived in the same house in Redlands, California, where her son, and his wife were building at least 15 pipe bombs and stockpiling thousands of rounds of ammunition.

The father told La Stampa that his son "shared the ideology of al-Baghdadi, and was obsessed with Israel,".  He counseled his son to be patient because in time political changes in the Middle East will accomplish his desires, in two years Israel will no longer exist.

"See something say something" that should be the law, similar to the Good Samaritan Law.    Family members, a mother, a father, a sister, or a brother, of a killer shouldn't have a life in USA if they didn't report.

 There is no lone wolf in our days. Their are people who  look the other way and that is a crime.

Just a thought.
